#4 Luke Harper
It took a long time, but in 2017, former Wyatt Family members Luke Harper and Erick Rowan finally stepped out of their former leader Bray Wyatt's shadow.
They spent several months hammering enhancement talent, before becoming WWE SmackDown Tag Team Champions at WrestleMania 34. They lost the titles to The New Day on the post-SummerSlam edition of SmackDown, after a 135-day reign. The decision came after it was revealed that Rowan had suffered a torn right bicep, sidelining him until 2019. And with that also came Luke Harper's departure from TV.
No, Luke isn't injured too. But after spending so long as a tag team wrestler, WWE creative just don't know what to do with him, and that is such a shame. As of this writing, Luke has only wrestled two matches since Rowan's injury, and both were at NXT live events. Luke is a very talented performer, and although it was short, he has proven he can have a solo career as he won the WWE Intercontinental Championship in 2014.
Yes, I would like to see the reunion of The Bludgeon Brothers on SmackDown next year to continue their brutalizing ways, but until then, I think Luke would fight right in on the WWE United States Championship contender ranks.
